(PG) is known as a high-potential material in terms of its biological activity. The objective of this report is to provide chromatographic and mass fragment ion data of 38 simultaneously identified saponins, including novel compounds, by analyzing them through ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QToF/MS). In so doing, we investigated their diverse conditions, including morphological parts (stems, roots, buds, and leaves), peeling (or not), and blanching of PG. The total contents of individual saponins indicated an order of roots (containing peel, 1674.60 mg/100 g, dry weight) > buds (1364.05) > roots (without peel, 1058.83) ≈ blanched roots (without peel, 945.17) ≈ stems (993.71) ≈ leaves (881.16). When considering three types of aglycone, the platycodigenin group (55.04 ~ 68.34%) accounted for the largest proportion of the total content, whereas the platycogenic acid A group accounted for 17.83 ~ 22.61%, and the polygalacic acid group represented 12.06 ~ 22.35%. As they are classified as major compounds, novel saponins might be utilized for their role in healthy food for human consumption. Additionally, during blanching, the core temperature of PG was satisfied with the optimal condition, thus activating the enzymes related to biotransformation. Furthermore, through the use of this comprehensive data, additional studies related to buds, as well as roots or the characterization of individual saponins, can be conducted in a rapid and achievable manner.
(PG)因其生物活性而被认为是一种具有高潜力的材料。本报告的目的是通过超高效液相色谱-四极杆飞行时间质谱联用仪(UPLC-QToF/MS)对 38 种同时鉴定的皂苷进行分析,提供其色谱和质谱碎片离子数据,包括新化合物。通过这种方式,我们研究了它们在不同条件下的情况,包括形态部分(茎、根、芽和叶)、去皮(或不去皮)和 PG 的烫漂。单体皂苷的总含量顺序为根(带皮,1674.60mg/100g,干重)>芽(1364.05)>根(去皮,1058.83)≈去皮根(烫漂,945.17)≈茎(993.71)≈叶(881.16)。考虑到三种苷元类型,远志糖基组(55.04%68.34%)占总含量的比例最大,而远志糖酸 A 组占 17.83%22.61%,聚半乳糖酸组占 12.06%~22.35%。由于它们被归类为主要化合物,新型皂苷可能因其对人类食用健康食品的作用而被利用。此外,在烫漂过程中,PG 的芯温满足最佳条件,从而激活与生物转化相关的酶。此外,通过使用这些综合数据,可以快速、可行地对芽、根或单体皂苷进行进一步研究。
